Perfectly balanced soil for turf
The soil pH is an ideal 7.01, requiring almost no chemical adjustment for most grass varieties. This well-drained gravelly clay loam provides the structural support and aeration that roots need to grow deep. It is one of the better soil foundations found in the region, supporting a wide variety of landscaping options.
Severe drought despite good rainfall
While annual rain is good, 90.2% of the county is currently in severe drought after 37 weeks of dry conditions over the past year.
